United States Patent 2,851,106 SIDE CONNECTION FOR WELL cAsINGs 7 Robert W. Dicken, Arcadia, Ohio Application May 18, 1954, Serial No. 430,596 1 Claim. (Cl. 166-88) This invention relates to wells.

An object of this invention is to provide a well casing with a side wall outlet and inlet to be attached at a predetermined longitudinal position along the casing.

Another object of this invention is the method of effecting the assembly of the parts.

Another object of this invention is to provide a leak proof by-pass through the side wall of a Well casing.

And another object of this invention is to provide a fitting to be associated with a well casing, which fitting provides a plurality of by-passes through the casing and seals the same against leakage thereabout, both into and from the casing, and furthermore defeats roots and the like from growing into the casing.

Other objects and advantages of this invention relating to the arrangement, operation and functions of the related elements of the structure, to various details of construction, to combination of parts and to economies of manufacture, will be apparent to those skilled in the art upon consideration of the following description and appended claim, reference being had to the accompanying drawings forming a part of this specification wherein like reference characters designate corresponding parts in the several views.

Referring to the drawings:

Fig. 3 is a view on the line III-III, Fig. 2; and

Fig. 4 is a view on the line IVIV, Fig. 2.

In wells, particularly those for supplying water from a sub-surface source, sections of casings are suitably assembled to provide a continuous duct 12 from a water supply to the surface 14 of the ground. This casing serves to house pipes 16, 18, which extend through the casing from the fluid source to a suitable pumping installation, such as a two-duct type pump conveniently located to the well and the point or points of final delivery.

As a general rule, these pipes 16, 18 project through the upper terminus 20 of the casing 10 to extend to the pump. However, in localities where sub-freezing temperatures occur, this arrangement has proved to be a source of trouble due to freezing.

It is a prime purpose of this invention to provide a side delivery from the casing which may be installed below the frost line and thus adapt the well to year round service.

To this end, a trench may be dug to expose a casing section sufficiently below the danger line, and longitudinally aligned apertures 22, 24 cut through the casing wall. Casting 26 includes a pair of duct sections 28, 30; the duct section 28 is provided with an angle branch 32 terminating in exterior and interior threaded outlet or port 34. The duct section 30 is provided with a similar angle branch 36 terminating in an exteriorly and interiorly threaded outlet 38. The ends of said ducts remote from the outlets 34, 38 terminate in a pair of in- 2 teriorly threaded radially aligned ports 40, 42. These ports 40, 42 are disposed in a common plane and are threaded to receive adapters which in turn serve as connections between the casting 26 and the pipes 16,18, which may vary in diameters in different installations. The ports 34, 38 are in alignment and disposed in a com mon plane intersecting the plane of ports 40, 42.

Thus, the casting involved herein provides two offset right angle ducts which extend from the lower horizontal plane of the ports 40 and-42 vertically upwardly one above the other, then at right angles horizontally inwardly'toward each other until they are in vertical alignment, and then at right angles forwardly, or radially outwardly with respect to the casing 10, to form vertically aligned outlets 34 and 38 in a vertical plane at right angles to the plane of the ports 40 and 42 and with orifices or openings substantially parallel to the plane of the two vertical portions of the duct sections 28 and 30.

The upper portion of the casting 26 is provided with a lug or boss 44 having a threaded seat 46 therein adjacent an opening 48 extending transversely through the lug.

In a typical installation, the header 26 may be assembled above ground with the pipes 16, 18, including the necessary adapters, connectors and the like, and a cable is attached to the opening 48, by which the assembly may be lowered into the casing 10 until the vertically aligned outlets 34, 38 are in registry with the apertures 22, 24. The outlets are then shifted to extend through said apertures to be exposed exteriorly of the casing.

in the event the cable attachment lacks stability to effect an assembly, a rod may be threaded into the seat 46 to serve as a positioning guide.

Once the outlets are seated to extend through the apertures, compressible gaskets 50, 52 are placed above the exposed portions of the outlets. These gaskets are then abutted by washers 54, 56, in turn abutted by nuts 58, 60, which may be tightened on the exterior threaded surfaces of the outlets.

The washers 54, 56 have their inner faces developed along the radius of the casing and a circumferential bead 62 about the openings therethrough engage the gaskets and when the nuts are adjusted such bead 62 crowds the gasket into a secure seal about the respective outlets. The assembly, when complete and tightened, provides a fluid tight seal about each outlet which not only prevents leakage from the casing, but prevents the surface water seeping into the casing, and furthermore bars root growth into the casing.

The two aligned ducts are formed in a single casting with the outlets aligned and positioned in a predetermined pattern to register with the openings cut through the'casing wall, and with an assembly of a gasket, washer and nut accords a satisfactory unitary construction fully sealed.

It is to be understood that the above description of the present invention is intended to disclose an embodiment thereof to those skilled in the art, but that the invention is not to be construed as limited in its application to the details of construction and arrangement of parts illustrated in the. accompanying drawings, since the invention is capable of being practiced and carried out in various ways without departing from the spirit of the invention. The language used in the specification relating to the operation and function of the elements of the invention is employed for purposes of description and not of limitation, and it is not intended to limit the scope of the following claim beyond the requirements of the prior art.

What is claimed and desired to secure by United States Letters Patent:

In a tubular casing having a pair of pipes therein and a double elbow means for the ends of said pipes to extend them through to longitudinally aligned and spaced holes in the side of said casing spaced from an end thereof, said-elbow means comprising: a single casting having adjacent ports at one end thereof extending along the inside surface of said casing adjacent said two holes for attachment to said ends of said pipes, said single casting having a pair of externally threaded outlets for projection through said holes in said casing, a pair of offset right angled ducts in said casting connecting said adjacent ports separately with said outlets, gasket means on said outlets against the outer surface of said casing around said holes, separate internally threaded means fitting on each of said externally threaded outlets for clamping said gasket against said casing to fasten and seal said 15 2,693,975

casting to said casing, and support engaging means on the opposite end of said casting from said adjacent ports for employment in locating and holding said casting when it is being mounted in said casing.
